It wouldn't necessarily create a mismatch in settings, but the output of your phono preamp would go down thus making it quieter and seemingly less power which is what started you down this path to begin with. But cartridge stats and phono stage settings are really finding a good combo and reading up on it will take some time to understand the quirks. If you were to upgrade cart, the settings could and should sound just fine, but your output from your phono stage would go down from 0.88v (3.5mV with 48dB gain) down to 0.5V (0.5mV with 60dB gain). While that is not a large issue most of the time, it may get where your Saga is almost full volume. With gain setting #4, the forced 100 Ohm impedance would be too low and would sound quiet, dark and blah. Not a deal breaker, just something to keep in mind.
With getting into MC carts (and especially LOMC) you really have to watch your impedance settings as they will wildly effect the sound of your system. Too little resistance and things will sound bright and thin, but too much and you'll be quiet, dark and blah. LoMC do sound better for sure, but only when you can get it right with adjusting settings. When I built my phono stage, I went through 5 different resistor values to find a nice happy medium, so I got some good practice with a soldering iron.
Currently I'd say if you were making ONLY one change, you'd be better off with a phono stage upgrade. Given your setup, I'd suggest another option with multiple gain settings but also independent impedance and capacitance settings as well. Going back to my fat kid brain food analogy, the best steak (cartridge) prepared in a microwave (underperforming phono stage) will still not equal a great meal. Lol. I made that mistake buying my Benz Micro cart while still using that Project Tube Box. My Ortofon 2M Blue into my current phono stage would have been far superior to my Benz Micro into the Project. Point being, you'd set yourself up much better for current system and future upgrades with a better phono stage over a better cart. And if you were going for a better cart suited to your current setup, a Sumiko Wellfleet MM cart would be an easier plug n play than the Hana EL.
